How Does Significant Figures Calculator Work?
Significant figures are very important as such numbers are used to indicate quantities like length, mass, volume, etc. To find the significant figures in a given number the certain rules must be followed. These are given below:
- Rule 1: Except zero every digit is a significant figure.
- Rule 2: If a zero is placed between any two non-zero digits it is considered significant.
- Rule 3: If a zero is placed on the right of a non-zero digit, it is considered significant.
- Rule 4: A zero placed to the right of a decimal point and left of a non-zero digit will not be significant.
- Rule 5: A zero that is placed to the right of a decimal point and does not have a non-zero digit that follows, is considered significant.
- Rule 6: If a zero is placed to the right of the last non-zero digit after the decimal, it will be significant.
To simplify calculations, significant figures can also be rounded off using some prescribed rules.
